Abstract
We study the tests and the calibration of the H1 liquid argon calorimeter. We show that, for the modules carried out and tested at LAL, we get an accuracy of the argon gap measurement of 0.6%. The required precision for the hadronic energy calibration is 2%. We analyse the data taken at CERN. The negative crosstalk effect is understood, it is due to the calorimeter mechanical constants and it is corrected for in the analysis. The liquid argon impurity is measured and corrected for also. The calorimeter response is homogeneous and is practicly identical between different modules. A simple model of dead material correction is tuned to CERN data. This model corrects a significant part of the energy loss in dead material but it should be worked out more precisely. Weighting methods are applied to pions data. They improve the performances of the hadronic calorimetry, namely, their resolution and linearity with energy. Finally, we study the leptoquarks signal in H1.
